Abstract
High intensity femtosecond lasers are now routinely used to produce energetic particles and photons via interaction with solid targets [1-2]. However, the relatively low conversion efficiency of such processes requires the use of high repetition rate laser to increase the average power of the laser-induced secondary sources [3]. Furthermore, for high intensity laser-matter interaction, a high temporal contrast is of primary importance as the presence of an ASE pedestal (Amplified Spontaneous Emission) and/or various prepulses may significantly affect the laser-matter interaction processes by creating a pre-plasma on the target surface.
